The Science of Love the Aron Study

Putting Art Arons theory that danger can provoke passion to the test, an attractive female experimenter stands on a windy suspension bridge and asks a male participant to take part in an experiment.

She asked them to fill out a sheet then write a brief dramatic story based on a photograph. She then offered to explain the experiment over the phone. She stopped 20 men on a windy suspension bridge and stopped the same number of men on a sturdier bridge. The men who met her on the suspension bridge were more likely to call the experimenter and write more romantic stories.

What is Arons theory? How is this an example of excitation transfer?
